For a Linux command-line setup, use FFmpeg to read the station’s direct audio stream, add a still image or looped visual, encode the result, and send it to YouTube Live. YouTube’s encoder workflow for this broadcast needs audio and video, so a radio feed alone is not enough. Use the station’s published stream URL, confirm you have permission to rebroadcast it, and take the ingest URL and stream key from YouTube Live Control Room.
What you need before starting
- A direct audio-stream URL from the station. A webpage containing a player may not be the media stream itself.
- A still image or video loop to provide the visual component for the YouTube broadcast.
- A Linux system with FFmpeg installed, network access to the station and YouTube, and enough upstream bandwidth for the selected output.
- A YouTube channel with access to create a live broadcast, plus its current ingest endpoint and stream key.
- Permission to retransmit the station’s audio and use the visual asset. Technical access to a feed does not grant rebroadcast rights.
Use the station’s own published stream address or documentation and test that address locally. There is no universal method for extracting a direct feed from every web player; formats, access controls, and URLs vary by station.
Choose the Linux workflow
| Option | Best fit | What to consider |
|---|---|---|
| FFmpeg | A straightforward relay with a still image or video loop. | Command-line control; you must choose suitable input handling, encoding, and a way to supervise a long-running process. |
| Liquidsoap with FFmpeg | Radio-oriented scheduling or more involved audio processing. | Liquidsoap can coordinate a radio pipeline and use an FFmpeg encoder. Follow current YouTube transport and codec guidance rather than copying an older example’s settings. |
| OBS | A graphical, interactive setup on a Linux desktop. | Configure the audio and visual sources and YouTube destination in the GUI. It is most natural when a desktop session is available and maintained. |
There is no universal winner: the right choice depends on whether you need radio scheduling, whether a desktop is available, and how comfortable you are maintaining a long-running service. FFmpeg’s protocol documentation covers network protocols and muxers, while the Liquidsoap book illustrates a radio pipeline using FFmpeg and a YouTube RTMP destination: FFmpeg protocol documentation and Liquidsoap book.
Set up the YouTube broadcast
- Open YouTube Studio and go to Create > Go live to open Live Control Room. Create or select a broadcast using the visibility and schedule appropriate for your test.
- In the stream setup, copy the currently displayed ingest URL and stream key. Use RTMPS when YouTube offers it; it is YouTube’s recommended secure extension to RTMP. Keep the key private, do not put it in a public script or paste it into a public support request, and regenerate it in YouTube if it is exposed.
- Check the current encoder guidance for the protocol and output mode you selected. YouTube lists H.264, H.265 (HEVC), and AV1 video options, up to 60 fps, and recommends CBR with a two-second keyframe interval (not over four seconds). It recommends AAC or MP3 audio, 44.1 kHz for stereo, and 128 kbps for stereo audio. These are YouTube’s general recommendations and supported options, not a guarantee that every codec works with every protocol or encoder.
- Choose a resolution and video bitrate using YouTube’s current recommendation for that output mode and the upstream capacity of the Linux host. Do not assume one bitrate suits every resolution, frame rate, or connection.

Build the FFmpeg relay
The command depends on the station’s actual input format, the visual file, the installed FFmpeg build, and the YouTube ingest details. The FFmpeg protocol reference documents available network protocols, but it cannot establish a ready-made command for an unknown station feed. Treat the following as a command shape, not a copy-and-run recipe: replace each placeholder with a value verified for your setup.
ffmpeg -re -i "STATION_AUDIO_URL" -loop 1 -i "VISUAL_IMAGE_OR_VIDEO"
-c:v libx264 -preset veryfast -tune stillimage
-r OUTPUT_FRAME_RATE -g KEYFRAME_INTERVAL_IN_FRAMES
-b:v VIDEO_BITRATE -minrate VIDEO_BITRATE -maxrate VIDEO_BITRATE -bufsize VIDEO_BUFFER_SIZE
-pix_fmt yuv420p -c:a aac -ar 44100 -b:a 128k -ac 2
-f flv "RTMPS_INGEST_URL/STREAM_KEY"This illustrates combining audio and a visual input, encoding video and audio, and sending an FLV-muxed output to an RTMP-family ingest. Verify the station input and output options against your FFmpeg build and the current YouTube protocol guidance before using it. The keyframe interval must correspond to the output frame rate: for example, two seconds means twice the frame rate in frames. The example’s audio settings reflect YouTube’s general stereo recommendation; if the source is mono or has a different channel layout, make an intentional choice rather than assuming stereo content exists.

- Input: use the actual network URL and any input options required by its format. If the station uses a playlist, Icecast, or another transport, the correct demuxer and options may differ.
- Visual: a still image can be looped; a video can serve as the visual input. Confirm that the finished broadcast has a valid video signal as well as sound.
- Video encoding: the command uses H.264 as a common example. YouTube also lists other codecs, but compatibility depends on the ingest protocol and encoder.
- Rate control: CBR is the recommended mode. Set video bitrate, maximum, minimum, and buffer values consistently for the output you chose; the placeholders must be replaced with appropriate values, not left as text.
- Destination: use the precise ingest URL and key shown for your broadcast. Do not assume the endpoint format or key is interchangeable between streams.
For a radio schedule or processing chain, Liquidsoap can sit between the source and FFmpeg output. The Liquidsoap book includes an example using an FFmpeg encoder and YouTube RTMP destination; treat it as an illustration of pipeline shape and apply current YouTube codec and transport requirements.
Test before making the stream public
- Start with a private or otherwise controlled broadcast and run the relay.
- In YouTube Live Control Room, wait for the preview and inspect stream-health messages. Confirm that video appears, not just audio.
- Listen to the broadcast. Check for silence, clipping, distortion, unexpected pauses, and an unsuitable source volume.
- Watch long enough to catch interrupted input or visual playback. Confirm that the stream remains healthy before changing its visibility.
- After the test, stop the relay cleanly if you are not ready to broadcast continuously, and secure the stream key wherever you store it.
The YouTube Live Streaming API documentation describes live-stream resources, but your practical check for this workflow is the health and preview information shown in Live Control Room: YouTube Live Streaming API.

RTMPS or HLS?
For a typical FFmpeg relay, RTMPS is the direct starting point when the current YouTube setup provides it and your encoder supports it. HLS is a different ingest workflow, not simply an interchangeable URL: YouTube specifies HTTPS ingestion, MPEG-TS segments lasting one to four seconds, a rolling playlist with no more than five outstanding segments, and HTTPS POST/PUT. HLS also has higher latency because it sends segments. Check YouTube’s current setup requirements before choosing it: YouTube HLS setup.
| Consideration | RTMPS | HLS |
|---|---|---|
| Ingest approach | Secure RTMP extension recommended by YouTube. | HTTPS ingest with segmented MPEG-TS and playlist requirements. |
| Latency | Use the latency setting and behavior available in YouTube Live Control Room; the encoder guidance does not establish a single latency for every setup. | Higher latency because the stream is sent in segments. |
| Configuration burden | Requires a compatible encoder and the current RTMPS endpoint and key. | Requires HTTPS POST/PUT, one-to-four-second segments, and a rolling playlist of no more than five outstanding segments. |
Keep a Linux relay running unattended
A Linux VPS is one possible place to run a continuous relay if you do not want to keep a desktop computer on. It is optional, not a requirement, and the host must have adequate network capacity and a reliable way to monitor and restart the process. A VPS does not make a stream failure-proof: the station feed, network route, host, encoder process, or YouTube ingest can still fail. No particular provider, service level, or bandwidth plan is established here, so compare those against your expected stream bitrate and operating needs.

For a process you manage yourself, arrange monitoring and restart behavior appropriate to your Linux distribution and deployment. Check logs and YouTube stream health after a restart; a process running again does not by itself confirm valid audio, video, or a healthy broadcast.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Common problems and fixes
- FFmpeg cannot open the station URL: verify you are using the published media-stream URL, not just the station’s player page. Check the station documentation and whether the feed needs particular input options or credentials.
- YouTube shows no video: check that the visual input is being read and mapped into the output, and that the selected encoder and protocol are compatible. A radio feed supplies audio only.
- The stream key or destination is rejected: copy the endpoint and key again from the selected Live Control Room stream. Do not reuse an old key or alter the endpoint by guesswork.
- Audio is silent, clipped, or in the wrong channel layout: inspect the source feed and FFmpeg input/output audio settings. Test levels and listen to the private broadcast before going public.
- The stream health is poor or it disconnects: compare the selected output bitrate with the available upstream bandwidth, inspect FFmpeg output and host/network logs, and check Live Control Room’s health message. Lowering resolution or bitrate may help if the connection cannot sustain the chosen output.
- It stops after a host or process failure: investigate the reason in system and FFmpeg logs, then configure supervision and alerting. Restart behavior can restore a process but does not guarantee the feed or YouTube ingest has recovered.
- The station asks you to stop rebroadcasting: stop the relay and resolve permission directly with the station or rights holder. A technically accessible stream is not necessarily licensed for retransmission.
Copyright and YouTube policy
Before relaying a station, confirm that its terms permit rebroadcast on YouTube and that you have rights to any music, spoken content, and visual material. Permission to listen to a station does not establish permission to retransmit it. YouTube may also apply its own copyright and live-stream rules; review the current terms for your channel and content before broadcasting. The rights status of any particular station is not established by the fact that its feed is reachable.
